WWNL features local and national religious leaders, including Charles Stanley, John MacArthur, David Jeremiah and Michael Youssef.
Because AM 1080 is a clear channel frequency reserved for Class A stations KRLD Dallas and WTIC Hartford, WWNL is a daytimer, required to sign off the air at night.
Unable to compete with KQV in the Top 40 format, WEEP changed to country music in 1965, in which it enjoyed its greatest success.
Most large cities in the north did not have a radio station playing country and western music, so WEEP was alone in the format for many years.
Based on WEEP's good ratings, the owners switched WEEP-FM (now WDSY-FM) to country music as well, a first such FM station in Pittsburgh.
In February 1992, the call letters were changed to WDSY and the station became a full time simulcast of WDSY-FM's country format.
